How do I use a cached/baked smoke simulation with command line rendering?
This worked for cloud rendering via command line, as for a local computer or render-farm, I don't know.

Change the cache baking location with the file path " // ". It should auto-name it if it doesn't accept a custom name.

Save the .blend file, bake the simulation and it will appear where you saved the .blend. Therefore blender will "look" in the same folder, a dedicated location.

How do I re-Load Fluid Sim Cache?
